The EN pin turns off every channel so that all Source pins are disconnected from the Drain pins. Without the EN pin, either SxA or SxB will be connected to Dx, depending on the state of the INx pin.

The switches are high impedance when the EN pin is set HIGH, but the voltages that can be applied to the source or drain pins must still remain within the supply voltages, or else you will exceed the Absolute Maximum Ratings.
